I appreciate Opera is in bed with Google but… …
If you want to get rid of advertiser loading on your Google searches add this search algorithm to your query:
How does it work?
When you put a minus sign on the serch the engine looks for your words on the web and then combs out all the spurious stuff that has words you don't want to appear. E.g.:
A search for…
"black horse" -pub
…will get you a list of websites about black horses but not including pubs called The Black Horse.
What the above "-inurl" removes from the search is business sites such as Kelkoo, Bizrate, Pixmania, Dealtime and etc.
Now I want to find out how to add the web site:
to Opera (or, on this computer) Firefox.
